Taiana came and distracted Reiter allowing her and Oliver to escape with the idol which soon begins to affect Taiana and she is holding the idol.

Overall I enjoyed the episode; it was nice to see Felicity working with her father and kind of experience where she got her brilliance. I enjoyed the Diggle and Oliver talk about not being honest with Lyla using and Felicity’s relationship and an example. Lyla saving Diggle was totally hot and proves that she is a badass not like we didn’t already know she kicks ass. I was shocked by Alex response to ending the world. But still confuse to whether or not he have been brainwashed or he is there of his free will. Noah jumping in front of a bullet to save Felicity makes me think he had some redeeming qualities and was funny see Noah trying to bond with his son in law even though he doesn’t think that he is who he is.
